Subject Review Request 66144: Enforced task launch order on the agent.

Review request for mesos, Chun-Hung Hsiao and Greg Mann.

Bugs: MESOS-8624

Repository: mesos


Up until now, Mesos does not guarantee in-order
task launch on the agent. There are two asynchronous
steps (unschedule GC and task authorization) in the
agent task launch path. Depending on the CPU scheduling
order, a later task launch may finish these two steps earlier
than its predecessors and get to the launch executor stage
earlier, resulting in out-of-order task delivery.

This patch enforces the task delivery order by sequencing
task launch after the two asynchronous steps, specifically
right before entering `__run()`.
